NameError：名稱“pytest”未定義 - GitHub 操作

Question

我有一個簡單的Docker圖像，其中包含一些 python 測試用例。

這是我的Dockerfile

ARG PYTHON_VERSION=3.8.3-alpine

# Use the python image as the base image
FROM python:${PYTHON_VERSION}

# upgrade pip 
RUN pip install --upgrade pip

# set CUSTOMER_NAME as environment variables
ENV CUSTOMER_NAME=${CUSTOMER_NAME:-A}

# Set the working directory 
WORKDIR /app

# Create a non-root user and add the permissions
RUN adduser -D "${USERNAME:-jananath}"

# set the username - HERE WE ARE USING A DEFAULT VALUE FOR THE USERNAME, WHICH IS "jananath"
USER "${USERNAME:-jananath}"

# copy the requirements file and install the dependencies
COPY --chown="${USERNAME:-jananath}":"${USERNAME:-jananath}" requirements.txt requirements.txt
RUN pip install --no-cache-dir --upgrade --user -r requirements.txt

ENV PATH="/home/${USERNAME:-jananath}/.local/bin:${PATH}"

# copy the app code
COPY --chown=${USERNAME:-jananath}:${USERNAME:-jananath} . .

# expose the default Flask port
EXPOSE 80 

# set the entrypoint to run the app
CMD ["uvicorn", "main:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "80"]

然后我構建圖像：

docker build -t hello:v1 .

然后我運行應用程序

docker run --rm -itd -p 80:80 -e CUSTOMER_NAME=A hello:v1

然后我執行pytest

docker exec -it 570e3153ab90 pytest

它成功地給出了pytest output 如下：

================================================= test session starts =================================================

一切正常，除了我在`GitHub Actions 中運行相同的圖像。

. . .
  container-test-job:
    runs-on: ubuntu-latest
    container:
      image: ghcr.io/<USERNAME>/<REPO>/hello:v2
      credentials:
          username: ${{ github.actor }}
          password: ${{ secrets.TOKEN_REPOSITORY }}    
      env:
        CUSTOMER_NAME: A
    steps:
      - name: Test
        shell: python
        run: |
          pytest
. . .

但我收到以下錯誤：

追溯（最近一次通話最后一次）：文件“/__w/_temp/598eea6e-7acf-4d7c-964f-a69440ea38c2.py”，第 1 行，在 pytest NameError：名稱“pytest”未定義錯誤：進程已完成，退出代碼為 1 .

有人可以幫我理解這里的問題以及如何解決嗎？

謝謝！

嘗試此代碼，然后您可以構建圖像並將其推送到您的注冊表。

name: build and test

on:
  push:
    branches:
      - "main"

jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Set up Python 3.10
      uses: actions/setup-python@v4
      with:
        python-version: 3.10.6
        architecture: "x64"

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install pytest
        if [ -f requirements.txt ]; then pip install -r requirements.txt; fi

    - name: Test with pytest
      run: |
        pytest
